(Cl. 24v- 69) 3 Claims.

This invention relates to weather stripping.

One of the principal objects of the invention is to provide a weather stripping for a window having vertically sliding sashes, which shall be adjustable to windows of different widths.

Another object is to provide weather stripping adapted for both upper and lower` sashes of windows, and which may also be used if desired for doors or for windows of types other than doublehung.

Another object is to provide a weather stripping construction which shall be effective in excluding drafts, cold air, and dust, from the room.

Another object is to provide a stripping which shall reduce rattling of the window or door.

Another object is to provide a stripping which can be simply and easily installed. v

Further objects and advantages of the invention will be in part set forth in the following specification, and in part will be obvious therefrom without being specically pointed out.

With the above and other objects of the invention in View, the invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as set forth in the claims hereof, certain embodiments of the same being illustrated in the accompanying draw-- ing and described in this specification.

Referring to the drawing which forms a part of this specification:

Fig. 1 is an elevational View, partly in section, of the lower part of a window casing, looking from within the room, showing one embodiment of my invention installed, the window sash not being shown;

Fig. 2 is a vertical section taken along the line 2 2 of Fig. 1, but also showing the full depth of the casing and showing the lower sash closed against the weather stripping;

Fig. 3 is a sectional View, looking toward the right relatively to Fig. 1, but showing a vertically central portion f the side casing and showing in section adjacent portions of an upper and a lower sash in closed position and the portion of an embodiment of my invention constructed for use in this location;

Fig. 4 is a perspective View, on an enlarged scale and partly broken away, of the portion of the device shown in section in Fig. 3, in an inverted position to better illustrate the construction; and

Fig. 5 is a perspective View on a reduced scale of a modication of the device shown in Fig. l, showing integral attaching means therefor.

Referring rst to Figs. 1 and 2., Ill and II indicate the bottom and side members ofA a window casing of a double-hung window, and I2 and ILl indicate relatively slidable members of my weath er stripping. These members are formed of thin sheet metal, and comprise base portions which lie upon the sill under the sash, longitudinal vertical portions I5 and lrespectively, and verti cally extending leaf portions II and I8 for attachment to the sides of the casing.

The vertical portion IB of the member I4 has an overturned flange 20, forming a Achannel with. in which slides an overturned edge 2| of the vertical portion I5 of member I2, thus interlocking the strips in slidable relation until secured in place. The flange 20 and edge ZI may be'cut away at their outer ends to avoid interference with the vertical members 22 of the casing which guide the window sash (see also Fig. 5), or lie against the same as shown.

Vertical leaf-members Il and I8 extend at right angles to the base portions of strips I2 and I4. and serve for attachment at the sides, and also to increase the closeness of the t of the sash in the casing and reduce the space thru which air might pass. As shown in Fig. 1, their upper 5' ends are secured to the casing by short nails 23.

The base portion of member I2 is provided with a longitudinal slot 24, thru which screw 25 may pass, and a perforation for a nail 26. The base portion of member I4 has a perforation for a nail 2l, and has a perforation only for the screw 25.

In installing this portion of the device, the members I2 and lll are interlocked by means of the flange 2U, thus holding the same in parallel but slidable position. The resulting unitary de vice is then placed in position and extended as far as possible, to fit closely against the sides of the casing, the angles between the bases and the leaves Il and I8 tting closely into the runway of the sash. The screw 25 is placed thru the perforation in member I4 and passes thru the slot 24 into the sill Ill of the casing, the nails 2E and 2'! securing the side poritons of said base. The leaves I'I and I8 are fastened closely to the side casing by nails 23.

It will thus be seen that the strip is adjustable closely to any size of casing, even to fractions of an inch, as the interlocking members may be adjusted to any length, the nails 26 and 2l will hold the same in extended position, and the screw 25, providing a heavier hold for the double portionV of the strip, may pass thru any point in the slot 2li in the lower member I2, as may be required. Obviously, such installation can be done by anyone, without difficulty and without the ne,

cessity of making holes, using any special tools, etc., etc.

As shown, the strip just described is installed at the bottom of the lower sash 28 of a doublehung window, and with the flanged edges outside (see particularly Fig. 2). If desired, the same may be used in other locations, such as the top of a window or door, or in any other place in which it will fit, and the same may be installed withV the flanged edges inward krather than outward as shown. The same strip, without change, can be used in any of said positions.

The same should be installed so that the flanged edge will lie closely against the face, inner or outer, of the sash or door as the case may be, and will serve not only to check drafts and the passage of cold air, but to keep out dust, and, by reason of its resiliency, to check rattling. of the window or door.

Thev strip' above described maybe formed from either iiexible or relatively inflexible.- metal; and more'or less resilient as desired;v this is also true of the embodiment shown-infFigs; 3 and 4, about to be described. The form shown inv Fig". 5, below described, is preferably somewhat exible, as-will be evident, to permit installation by means of the integral attaching means there shown: and described.

In Figs. 3 and 4, I have shown the str-ip modiedto t the junction of the'upper and lower sashes of adouble-hung, window. In this case, members and' 3| are provided, having inter, locking edges 32 andl 33 respectively; analogous to the edges 2U and2l above described, and hav- 1 ing also anges 318 and 34,.riding against each other and serving to check the passage of air at the crack between the' s'ashes, as well as to hold the members in alignment, in co-operation with 32 andV 33. Both-strips are c'ut out at their .a

corners as indicated at 35 on strip 30 (see Fig. Il)v to permit the samev to t around the guiding members 22 of the casing. The: member 3| has a slot 36 and a nail-hole (not'shown), and the member 3D has a screw-hole 31 and a nail-hole 38 (see Fig. 4), by-meansof all of which the' device' may be secured by a' single screw' and a pair of nails, not shown, in a manner entirely anal'- ogous to the base'portion of the device above described. The same is shown in place on the lower edge of the upper sash 29, having the flanges 34 and 34' extending downward.` Obviously the same may if preferred be installed with said flanges extendingupi'rardv` into the crack between the sashes 23 and 29, in which case the flanges would be somewhat inclinedt to nt the angle of the abutting surfaces of the sashes', and must be made o'f suciently'thin material;

In Fig. 5, I have shown a' device similar' to that of Figs. 1 and2, except that instead of providing, for the same being secured in placeiby nails and a screw, triangular lugsofmetalll areJ struck out from the material itself, which' may' be merely hammered into place in the casing, the thinness of the metal in this constructionf providing' a sufficiently sharp edge for this purposeV in a casing' of wood such asoften used: for such purpose.

As shown, lugs dfstruck' from the base portions of member 42 and 411, se'rvethe` same purpose' as nails 26v and' 2T, and lugs 413" on. the Vertical leaves take the place of nails 23:- A cer'itralr lug 4 I`, struck out' from the uppersliding member M, passes thru a'- slot'` (not shown) ini the member 42, analogous to slo'tl 24,A at any desired` point,

and secures the double portion of the unitary assembly in place, in lieu of the screw 25, and in the same manner.

By these means, the device may be secured to the sill by the use of a hammer only, with no loose nails or screws, and after fitting the same closely into the corners of the runway, the upright leaves secured by hammering in the lugs 40. Lugs functioning in a similar manner t0 lugs 40 and 4| may obviously be used also on the uppersashstrip.

The operation and many of the advantages of my invention have been referred to in what is above said, and need Inot be recapitulated here.

I do not limit myself to the particular details of construction above set forth, as the same refer to and describe only certain embodiments of my invention, and it is obvious that the same may be modified, within the scope of the claims hereof, without departing from the spirit and scope of my invention. l

Having thus describe-d my invention, I claim:
